Maybe some writers are just too self-absorbed to get this one right. All too often when editing, I see sentences like The boss handed the project off to Laura and I.

What if Laura wasn’t part of the equation, though? You wouldn’t write The boss handed the project off to I. Instead, you’d write The boss handed the project off to me.

If using the word to, use me rather than I. If “you” are the subject of the sentence, then use I as in I handed the project off to Laura and that flunky writer.
